| 摘 要： | 平面连杆机构的位移分析中一个困难问题是给定一个主动杆位置求其他各杆位置时存在多解,在用计算机求解编排程序时,要明确指出所需的那个解。求复杂平面连杆机构的位移分析常常可归结为方程式求根问题,存在多根表示连杆机构可能工作在不同区段,本文提出一种划分平面连杆机构工作区段的方法。从数学上来说,就是用“根分离法”来求解方程式。此方法对六连杆机构全部适用,八连杆机构大部份适用,也可用于更多杆件的机构中。

| Abstract: | The difficulty in the displacement analysis of a complex plane mechanism isthat for a given input link position there may exist several position solutions ofother links, and the required solution must be definitely specified when it is to besolved with a computer. The displacement analysis of complex plane mechanismsis usually reduced to a question of solving equations. Existance of several solu-tions means the possibility of linkage motion in different domains. This paper pre-sents a method to separate the domains of the linkage movement. In the mathema-tical sense this is to solve the equation by means of separation of roots. Thismethod can be applied to all the six-link mechanisms and most of the eight-linkmechanisms, as well as certain mechanisms of even more links. |
